CFS model data files are updated each day after the 18Z set of runs. Data files are not for individual model runs, but are an average of the last 40 runs in order to match up with what appears on the NOAA CPC page. One global file contains forecasts for specific site locations, the other contains forecasts on a lat/lon grid.

*Anomaly Only data files are an average of the temperature anomaly at each 6 hour forecast interval, other data files contain the anomaly as calculated from the model forecast Max/Min. The values in the Anomaly Only files tend to be more accurate since they are calculated using the 1981-2010 model climatology at each 6 hour interval, and is less influenced by model max/min biases.
